Ocular Disease Diagnosis and Treatment
Preserving the eyesight of our patients so they can get the most out of life is our greatest goal. Our Eye Care Clinic makes it a policy to ensure that all staff members are up-to-date on the latest technology and techniques to make your visit as comfortable and effective as possible. As optometric technology changes, it is even more important to visit an eye doctor who has all the right optometry qualifications and follows the latest developments in eye care.
Utilizing cutting edge technology, we diagnose and manage, with greater precision, diseases like Glaucoma, Macular Degeneration, Cataracts, and Diabetic Retinopathy. Earlier and more precise diagnosis means earlier treatment and better outcomes. We can take an aggressive approach to diseases that previously had few treatment options. Great advances have been made in the treatment of these diseases.
Cataracts is a disease of the eye that results in the clouding of the lens of the eyeball. Cataracts prevent clear images from appearing on the eye’s retina; causing mild, moderate, even severe blurred vision.
Typically an eye disorder associated with aging (over half of the people in America over age 80 have either had a cataract or cataract surgery), cataracts generally occur later in life as the lens structure within the human eye changes and gets older. In addition to age, other risk factors that lead to cataracts include smoking, UV overexposure and diabetes.
During the evaluation of your eye health we will carefully examine your lens for signs of cataract formation. If a cataract is noticed and the clouding is causing visual disruption, the optometrist will refer you to a trusted and respected surgeon for surgery, which is the only known cure for cataracts. Our Eye Care Practice will be there for you providing pre and post cataract surgery care.
Cataract surgery is the removal of the natural lens of the eye (also called “crystalline lens”) that has developed an opacification, which is referred to as a cataract. Metabolic changes of the crystalline lens fibers over the time lead to the development of the cataract and loss of transparency, causing impairment or loss of vision. During cataract surgery, a patient’s cloudy natural lens is removed and replaced with a synthetic lens to restore the transparency of the lens.
Following surgical removal of the natural lens, an artificial intraocular lens implant is inserted (eye surgeons say that the lens is “implanted”). Cataract surgery is generally performed by an ophthalmologist (eye surgeon) in an ambulatory (rather than inpatient) setting, in a surgical center or hospital, using local anesthesia (either topical, peribulbar, or retrobulbar), usually causing little or no discomfort to the patient. Well over 90% of operations are successful in restoring useful vision, with a low complication rate. Outpatient care, high volume, minimally invasive, small incision phacoemulsification with quick post-op recovery has become the standard of care in cataract surgery all over the world.
Cataracts are one of the leading causes of vision loss in people over 45. A condition that commonly develops as the eye ages, by the time we reach 80, more than half of us will have developed a cataract.
A cataract is a clouding of the lens in your eye which is normally transparent. The lens, located inside the eye, behind the iris and the pupil, focuses light onto the retina at the back of your eye, where it is converted to nerve signals that are passed to the brain, allowing you to see. When your lens becomes cloudy, the images projected onto your retina become blurry and unfocused and therefore the signal to the brain is also unclear. You can compare this to looking through a dirty or cloudy window. If the window is not clear, you can’t see well.
Usually cataracts develop slowly over time so your vision gradually worsens. While the majority of cataracts are a result of the aging process, there are also congenital cataracts that are present at birth, secondary cataracts that result from eye surgery or diseases such as glaucoma or diabetes and traumatic cataracts that result at any age from an injury to the eye.
While you may be able to live with mild or moderate cataracts, severe cataracts are treated with surgery. The procedure involves removing the clouded lens and replacing it with an intraocular lens (IOL) implant. Cataract surgery is a common procedure that has a very high success rate of restoring vision to patients. Modern cataract surgery is frequently done as an outpatient procedure. Patients will have greatly improved vision the next day, and will continue to improve over the next few weeks. Surgery is often done in one eye first, and surgery on the second eye, if needed, may be done 2 weeks later.

Though cataracts are often associated with aging—particularly men and women over age 60, people in their 40’s and 50’s are also more prone to developing cataracts. Research suggests that lifestyle factors like cigarette and alcohol use, diabetes and prolonged exposure to the sun’s harmful UV rays could all contribute to lens yellowing with age, and cataracts.
Other types of cataracts include secondary cataracts from surgery for other eye disorders like glaucoma; cataracts that form as a response to eye trauma or injury; cataracts that develop after exposure to certain forms of radiation; and in some cases, cataracts are congenital—you’re born with them.
The point is—with cataract symptoms and treatment, as with all things eyecare-related—there’s no substitute for a comprehensive, regularly schedule eye exam to check for vision problems and maintain healthy sight.

Treatment for cataracts involves surgery, but being diagnosed with a cataract does not mean that you need to have surgery immediately, or maybe ever. You may be able to live with symptoms of early cataracts for a while by using vision aids such as glasses, anti-glare sunglasses, magnification lenses, strong bifocals or brighter lighting to suit your needs.
Surgery should be considered when the condition begins to seriously impair your vision to the extent that it affects your daily life such as reading or driving, playing golf, playing cards, watching TV, etc. Sometimes surgery is also necessary if the cataracts are preventing treatment of another eye problem. The good news is that cataract surgery is typically very successful in restoring your vision. Together with your eye doctor, you will decide if and when the time for surgery has arrived.
Cataract surgery is one of most common surgeries performed in North America and has a 90% success rate (meaning the patient has improved vision, between 20/20 and 20/40 vision, following the procedure).
The surgery involves removing the clouded natural lens and usually replacing it with a clear, plastic intraocular lens (IOL) that becomes a permanent part of the eye. It is a relatively quick and painless procedure and you will not feel or see the IOL after the implant.
While development of cataracts is largely associated with age, there are other factors that can increase the risk of developing the condition. By knowing these risk factors, there are steps you can take to delay or prevent the development of cataracts:
- Sun Protection: Ultraviolet radiation can be a factor in the development of cataracts. It is recommended to protect your eyes from ultraviolet sunlight by wearing 100% UV protective sunglasses and a hat with a brim when you are exposed to the sun.
- Stop Smoking and Limit Alcohol Intake: These habits have been shown to increase the chances of developing cataracts, so if you smoke or regularly consume large amounts of alcohol – stop these habits.
- Proper Nutrition: Research shows that maintaining good health and nutrition can also reduce the risk of age-related cataracts, particularly by eating foods rich with vitamins A (beta-carotene), C and E and other antioxidants found in green leafy vegetables, fruit and a diet rich in Omega-3s.
- Regular Eye Exams: Once you reach the age of 50, or if you have diabetes or other eye conditions, it is important to have a comprehensive eye exam every year to check for signs of cataracts and other age-related eye conditions such as age-related macular degeneration or glaucoma. Early detection and treatment for many of these eye and vision disorders is often essential to save your vision.
Cataracts are part of the natural aging process of the eye and therefore, if you live to an old age, you will likely eventually develop one. While most cases of cataracts develop as part of this process, there are instances of congenital cataracts which are present at birth. Further, secondary or traumatic cataracts can occur at any age as a result of an eye injury, surgery or disease.While the risk of developing a cataract does increase as you age, it is not the only risk factor. Research shows that there are environmental, health and behavioral risk factors that can also play a role in cataract development. Many of these risk factors are avoidable and preventable. These risk factors include:
- Smoking and excessive alcohol consumption
- Prolonged exposure to ultraviolet (UV) radiation from the sun or other sources
- Certain medications such as steroids or statin medications
- History of eye injury or eye surgery
- Family history
Since they are largely a part of the the natural aging process of the eye, cataracts can’t necessarily be avoided, however knowing if you have additional risk factors can help you to take preventative steps to delay the onset of the condition.
